Does the Therapist's Assessment of Movement Control in Low Back Pain Patients Correspond to an Objective Kinematic Modification

Exercise-based treatment is part of the recommendations for good practice in the treatment of low back pain (acute, sub-acute and chronic). The low back pain population is heterogeneous. This heterogeneity would cause the positive effects of a treatment to be canceled out by the negative effects of another part of the population. This polymorphism has led several authors to classify low back pain into subgroups. These subgroups constitute more homogeneous clinical pictures and would facilitate the adaptation of treatments. The recommendations of the American Physical Therapy Association suggest 5 subgroups of low back pain. One of them is "low back pain with movement coordination defect". In this subgroup, Luomajoki studied the reliability of different functional tests used in clinical practice. 6 out of 10 motion control fault tests show good reliability. The quantified analysis of the movement of low back pain patients would make it possible to determine the sensitivity of detecting an anomaly in the 6 lumbar movement control tests.

This polymorphism has led several authors to classify low back pain into subgroups. These subgroups constitute more homogeneous clinical pictures and would facilitate the adaptation of treatments. The recommendations of the American Physical Therapy Association suggest 5 subgroups of low back pain. One of them is "low back pain with movement control impairment". In this subgroup, Luomajoki studied the reliability of different functional tests used in clinical practice. 6 out of 10 motion control fault tests show good reliability. The quantified analysis of the movement of low back pain patients would make it possible to determine the sensitivity of detecting an anomaly in the 6 lumbar movement control tests. LoBaCoM is a monocentric, exploratory prospective study. The purpose is to define a kinematic (angular) threshold corresponding to an anomaly detected clinically by three therapists for each test.

Each patient make six motion control fault tests in the same order : "waiters bow" "pelvic tilt" "one leg stance" "sitting knee extension" "rocking 4 point kneeling" "prone knee bend" This tests are performed three times.

Lumbar flexion measured for test number 1 "waiters bow". Patients are filmed during the test. Videos are watched by three physiotherapists. They going to establish a diagnostic normal or abnormal

thoracic flexion measured for test number 2 "pelvic tilt". Patients are filmed during the test. Videos are watched by three physiotherapists. They going to establish a diagnostic normal or abnormal.

Pelvic shift measured for test number 3 "One leg stance ". Patients are filmed during the test. Videos are watched by three physiotherapists. They going to establish a diagnostic normal or abnormal.

Lumbar flexion measured for test number 4 "sitting knee extension". Patients are filmed during the test. Videos are watched by three physiotherapists. They going to establish a diagnostic normal or abnormal.

Lumbar flexion and extension measured for test number 5 "rocking 4 point kneeling ". Patients are filmed during the test. Videos are watched by three physiotherapists. They going to establish a diagnostic normal or abnormal.

Lumbar extension measured for test number 6 "prone knee bend". Patients are filmed during the test. Videos are watched by three physiotherapists. They going to establish a diagnostic normal or abnormal
